Gestational trophoblastic disease encompasses a spectrum of trophoblastic lesions including true neoplasms such as choriocarcinomas and the potentially malignant hydatidiform moles, which may develop persistent disease requiring chemotherapy. ASPP1, a member of apoptosis-stimulating proteins of p53 (ASPPs), is a proapoptotic protein that can stimulate(More)
Gestational trophoblastic disease (GTD) includes frankly malignant choriocarcinoma (CCA) and placental site trophoblastic tumor and potentially malignant hydatidiform mole. p21-Activated kinase (PAK) 4 promotes cell motility. This study investigated the role of PAK4 in the pathogenesis of GTD. PAK4 messenger RNA and protein expressions in clinical samples(More)
In recent years, much attention has been paid to the concept of cancer stem cells (CSC) and self-renewal related pathways in cancer biology. This review outlines the dysregulated stemness-related genes or transcription factors in gynecological cancers. Hedgehog (Hh) and Notch signaling are important pathways in tissue pattern programming and cell fate(More)
DJ-1 is found to be important in human neurodegenerative diseases and cancers by regulating oxidative damage and apoptosis. DJ-1 is also a regulator of PTEN, a frequently mutated tumor suppressor gene in cancers. In this study, we investigated the expression of DJ-1 and PTEN in normal placentas and gestational trophoblastic disease in relation to apoptotic(More)
Human placental trophoblasts can be considered pseudomalignant, with tightly controlled proliferation, apoptosis, and invasiveness. Gestational trophoblastic disease (GTD) represents a family of heterogeneous trophoblastic lesions with aberrant apoptotic and proliferative activities and dysregulation of cell signaling pathways. We characterize the oncogenic(More)
Gestational choriocarcinoma is a malignant tumor derived from placental trophoblast and the most aggressive member of gestational trophoblastic disease (GTD). Apoptosis-stimulating protein of p53-2 (ASPP2) is a member of ASPP family that transactivates p53 and thereby functions as a tumor suppressor. In this study, the expression profile of ASPP2 in(More)
